The Origin Story
Chogadia Hisab brings Islamic astronomical timing calculations to mobile devices, based on knowledge from the Ikhwan-us-Safaa kitaab studied at Aljamea tus Saifiyah. The app calculates 12 hours of day (sunrise to sunset) and 12 hours of night (sunset to sunrise), with each hour influenced by different planetary forces.
Complex Math, Simple Glance
"Planetary hour calculations that once required referencing books and manual computation are now available at a glance, for any location in the world, not just the one you are standing in."
The Challenge
Bringing Islamic astronomical timing calculations to mobile devices required precise sunrise/sunset calculations and an understanding of planetary hour systems from classical Islamic astronomy.
Critical Pain Points
- Astronomical calculations must be precise for any location and date
- Planetary hours divide day and night into 12 unequal periods each
- Users need to check timings for any city, not just their current location
- Widget support required for quick access to current planetary hour
- Support needed for date range from 1900 to 2100
The knowledge from Ikhwan-us-Safaa kitaab studied at Aljamea tus Saifiyah needed to be translated into accurate algorithmic calculations that work anywhere in the world.
The Solution
Built a comprehensive planetary timing app using precise astronomical algorithms and user-friendly location management.
